对于许多患有发育性阅读障碍的儿童来说，除了解码之外，阅读流畅性是一个限制。为了矫正流利不良，需要在发展框架中探索和理解促成因素。本研究的重点是发展性阅读障碍的正字法加工，以及它如何有助于阅读流畅性。我们研究了正字法处理速度和准确性识别为阅读障碍的儿童，参加了密集的，流畅性为基础的干预，使用定时视觉搜索任务作为工具来衡量正字法识别。结果表明年龄和治疗效果，并描绘了快速字母命名和有效的正字法识别之间的联系。正字法效率与文章的阅读速度有关，但与拼写表现无关。正字法学习在阅读流畅性和补救的作用进行了讨论。
Reading fluency beyond decoding is a limitation to many children with developmental reading disorders. In the interest of remediating dysfluency, contributing factors need to be explored and understood in a developmental framework. The focus of this study is orthographic processing in developmental dyslexia, and how it may contribute to reading fluency. We investigated orthographic processing speed and accuracy by children identified with dyslexia that were enrolled in an intensive, fluency-based intervention using a timed visual search task as a tool to measure orthographic recognition. Results indicate both age and treatment effects, and delineate a link between rapid letter naming and efficient orthographic recognition. Orthographic efficiency was related to reading speed for passages, but not spelling performance. The role of orthographic learning in reading fluency and remediation is discussed.
